Remote Boom Positioner

The highest and lowest position of the bucket can be set

from the operator’s seat to match the height of any truck

body. Where the positioner is set will stop the bucket

smoothly without shock.

Selectable Traction Power and Travel Speed

● Maximum traction control: Traction can be set at any

level within 20 - 100% with the "TRACTION CONTROL

DIAL" located on the left front. You can set the maximum

traction force according to the condition of the road,

material and type of work. It greatly increases fuel

efficiency and extends the service life of tires.

● Maximum speed control: With the "VEHICLE SPEED

DIAL", you can set the maximum vehicle speed of 1st. and

2nd. at any level from

3km/h to max. This means

the operator can set the

cycle time between the

material and the dump

truck. As the loading cycle

time is shortened,

productivity is improved.

Dual-mode Active Working System

This system provides the most efficient hydraulic flow for your

operation. The active working switch has two modes:

powerful loading or normal loading.

The boom is raised

faster for shorter cycle

times. This combination

makes this mode

efficient for digging

Pump Neutral Cut Control System for Hydraulic Pump

The variable displacement piston pump combined with the

Pump Neutral Cut system, use only the required amount of

oil flow for the work, so it does not waste oil pressure. This

function reduces the fuel rate by controlling the pump

discharge, when not operating the work equipment.

Modulated Clutch System

When approaching the dump truck,

1) The current system requires the engine rpm to be increased to

raise the bucket faster. Now, the modulated clutch is controlled

automatically to raise the bucket faster, while reducing forward travel

speed. This reduction in travel speed eliminates the braking

requirement and the time to approach the dump truck is shortened.

2) This combination also reduces torque waste and smooths the

operation.

Variable Displacement Steering Pump +

Closed-center load sensing system

The variable displacement steering pump, combined with the

Closed-center load sensing system, delivers just the hydraulic

flow the steering requires. This prevents wasted hydraulic

pressure and contributes to increased fuel economy.

E P Control of Engine

The engine output function has "2 mode" of Economy or

Power. They are selected and controlled automatically. P

mode is selected only when digging and approaching the

dump truck. This "2 mode" engine control contributes not only

to the reduction of the fuel rate but also to the improvement

of reliability and durability.

gearing, are all Komatsu designed. Komatsu loaders are

manufactured with an integrated production system under a

strict quality control system.

Engine Pre-lube System

Engine durability is achieved by raising the oil pressure

before starting.

When the key is turned, the pre-lubrication pump sends oil

from the pan to the filter. When the set oil pressure is

reached, then the starter motor engages to start the engine.

Low Maintenance Brake System

The WA1200-6 uses Komatsu designed sealed wet disc

brakes. This proven design, coupled with a brake oil cooling

system, provides reliable and durable final drive braking while

downhill traveling with full loads and in all load and carry

operations.
